We study the estimation of preference heterogeneity in markets where consumers engage in costly search to learn product characteristics. Costly search amplifies the way consumer preferences translate into purchase probabilities, generating a seemingly large degree of preference heterogeneity. We...

Multivariate count models represent a natural way of accommodating data from multiple product categories when the dependent variable in each category is represented by a positive integer. In this paper, we propose a new simultaneous equation multi-category count data model ndash; the...

Targeting - setting marketing policy differentially for different customers or segments - is an important marketing practice. Previous approaches to quantifying the benefits from targeting have typically calibrated a response model and used the variation in response parameter estimates to...

For decades, statistical methods, many based upon the “general linear model,” have been used to do estimation and test hypotheses in the social and natural sciences, in medicine, and in the private sector. These tools have become increasingly sophisticated and are often paired with powerful...

Spatial models in retailing allow for correlations among purchase decisions from consumers within predefined geographic areas. The purpose of these models is to control for unobserved demand side effects at the regional-level (e.g., a neighborhood), but they typically ignore synergies among...

China has been experiencing the substantial changes in agricultural sectors in the past decades. Interaction between diversified channels for marketing agricultural products and modern technology adoption are important for restructuring agriculture and improving productivity, but fewer...
